我正在尝试执行一些操作，例如 - 在单独选项卡中的众多图表之一上绘制矩形。实际上，我有绘制矩形和滚动图表的功能，但它仅适用于最后创建的图表。我知道，这是合乎逻辑的，但是如何在其他选项卡中的先前图表上管理这些操作？我可以使用图表面板列表来获取这些数据集并向其中添加新值吗？怎么解决这个问题呢？谁能帮我？ SSCCE:

最佳答案
您的示例重写了 JFrame 及其 paint() 方法，以替换通常由 ChartPanel 提供的功能。相反，扩展 ChartPanel 并覆盖 paintComponent()，然后您创建的每个面板都将拥有一个具有新功能的图表。
- 您可以更可靠地控制可用的监听器。
- 您可以使控制面板可用，如图 here .
- 如 Painting in AWT and Swing: The Paint Methods 中所述，“Swing 程序应该重写
paintComponent()而不是重写paint()。”
关于java - 如何在单独的选项卡中管理多个图表上的操作 - jfreechart，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12561988/
